This document provides the necessary Bluetooth®/Bluetooth low energy and WLAN hardware operation information to aid in system design. This is a review of the integration process of TI's WiLink Module into final product PCB. When designing your own system around the TI module, it is recommended to step through the guidelines outlined below.
NOTE
You can check your TI module WL18XXMOD design to PCB integration with the WL18XXMOD series of easy-to-follow excel Checklist.

NOTE
Customers working with WL1837MOD/WL1807MOD modules that require only the single antenna solution (2.4 Ghz WLAN SISO/ Bluetooth/ 5 GHz single antenna), while reusing the original certification, can do so by making sure that no RF comes out of the second antenna port (2.4 MIMO only / 5 Ghz diversity). To do this, use the following requirements:
